Wireless Tether App works with xbox/MW2

last night my wifi crashed and i couldnt reset my router since my router is in my parents room and they were sleeping already, so i tested my wireless tether app on my xbox to play modern warfare 2, it actually worked flawlessly, on my wifi i have great speeds of 25 mbps download and around 5 up, but im never able to host since my connection is set to moderate, but when i used this even with the slow download speeds i was selected as a host and was able to play with absolutely no lag, and i actually got my first nuke ever

Wifi App is amazing. I use it for my computer (to type this right now) and on my PS3. There's literally no steps, download a wifi tether app, click the icon when you open the app up just like a flashlight app, and its go time. Pretty sure you gotta have root access, and probably 2.2 (thats what I have anyway), cuz everytime I switch it on it says "granted superuser access".
